Title: Seismic gas exploder arrangements
Inventor: STRANGE BOOTH BARRINGTON
IPC: G01V1/108
Filed: 1969-10-30
Abstract: 1,246,350. Generating combustion products under pressure. WESTERN GEOPHYSICAL CO. OF AMERICA. Oct.30, 1969 [Nov.29, 1968], No.53315/69. Heading F1L. [Also in Division H4] Effective scavenging of the gaseous combustion products from the combustion chamber of a seismic gas exploder is provided by a vacuumoperated exhaust system. In the Fig. 1 embodiment the combustion chamber is defined by an expandable sleeve 12 and end seals 14, 16 linked by tubes 38 through which tubes cooling water is funnelled when the exploder is towed by a ship. The exhaust system comprises a spring-loaded one-way valve 30 connected to a local vacuum chamber 52 exhausted by a ship-borne continuously operating pump 58 having a regulator 60 and vacuum reservoir 54. In use detonation of an explosive gas mixture fed from one or more lines 24, 28 is initiated in explosion chamber 18, whereupon sleeve 12 expands and then collapses as the pressure differential opens valve 30. The combination of the vacuum exhaust, the valve inertia and the combustion chamber cooling ensure that the combustion chamber pressure drops below atmospheric. Vacuum hose 56 need only be of narrow bore. If the fuelling and detonation steps are sufficiently rapid, several detonations can be produced within the open time of valve 30. A common reservoir 54, or several such reservoirs, may receive the exhaust from several gas exploders used simultaneously. Reference has been directed by the Comptroller to Specification 1,164,402.

Abstract: 1,207,150. Wear adjusters; clutch control. ACME-CLEVELAND CORP. 22 Dec., 1967 [27 Dec., 1966], No. 58501/67. Headings F2C and F2E. A brake or clutch 11, Fig. 1, has an axially fixed part 13 engageable by a friction lining 18 on a second part 12 axially movable by a sleeve 51 flanged at 54 and acted on by a spring or springs 50 when an actuator 29 moves from a first (off) to a second (on) position, the actuator 29 being slidable on the sleeve 51 and having a gauging surface 66 which is coplanar with a gauging surface 67 attached to the sleeve 51 when the brake or clutch is correctly adjusted by rotation of a rod 52 threaded into the sleeve 51. In a machine control application, the part 13 is non-rotatable so that the apparatus acts as a brake, and a lever system (31, 37, Fig. 2, not shown), moves the actuator 29 from its first to its second position under the control of a cam (41) or of a fluid cylinder 46. The flanged sleeve 51 acts on the movable brake part 12 through a plunger 24 and a thrust bearing 23, and the threaded rod 52 carries a washer 63 secured by a nut 62, the washer providing one gauging surface 67. The washer 63 seats on a recessed shoulder 68 in the actuator 29 when a return spring 26 holds the brake off, the clearance between the washer and the shoulder in the brake applied condition (Fig. 1) being such as to provide a predetermined spring pressure on the braking surfaces. Brake wear changes this spring pressure, and this is readily observable by non-alignment of the gauging surfaces 66, 67 when the brake is applied. Release of the nut 62, which acts also as a lock-nut for the rod 52 in the sleeve 51, permits the axial positions of the latter to be adjusted to align the surfaces 66, 67.

Abstract: 1370697 Stud-and-socket fastenings P C TABOR 16 Dec 1971 [18 Dec 1970] 58547/71 Heading E2B A fastener comprises a pin, at least the major portion of which is a solid right-circular cylinder, and a spring-steel sleeve the wall of which is imperforate except for an axial slit extending its entire length, at least the major portion of the sleeve being frusto-conical and of uniform taper, the interior surface of that major portion having no protuberances, and the diameter of its larger end being equal to or less than that of the said major portion of the pin, the sleeve having radially outwardly projecting flanges at its axially opposite ends, the outer diameter of the flange at the smaller end being equal to or less than the diameter of the larger end of the said portion of the sleeve. As shown, a sleeve 2, split at, 8 and formed to frusto-conical shape, has pin 14 first located with its tapered end 16 in the larger end of sleeve 2 and the assembly is then inserted first into a first opening 26 in a workpiece e.g. a clevis 18. A second workpiece e.g. a rod 28 having an opening 30 is located in the fork of the clevis, the opening 30 not needing to be exactly aligned with openings 26. The assembly 2, 14 is then moved through the substantially-aligned openings until flange 4 on sleeve 2 abuts the outer surface of clevis leg 22 as in Fig. 3. Thereafter pin 14 is forced to the left to expand sleeve 2 into cylindrical form. The diameter of sleeve 2 adjacent flange 4 may be slightly larger than that of the workpiece openings. Preferably sleeve 2 has a further flange 6, and a groove 32 forming a bead 34 which engages a groove 36 on the pin in the final position, (Fig. 4, not shown). The parts are however undamaged and de-mountable. Substantial mis-alignment of openings 26, 30 may be overcome by providing in and on the end 6 of sleeve 2 an expandable tapered pilot member (37), (Fig. 5, not shown), preferably of plastics material, the free end of the protruding part having a diameter much smaller than that of flange 6. When the assembly is in position, and the pin is in the position of Fig. 3, the pin will have pushed the pilot member out of the expanded end of sleeve 2. Bead 34 and groove 36 may be omitted.

Abstract: 1317447 Character recognition DATA SOURCE CORP 2 June 1970 [2 July 1969] 58799/69 Heading G4R Characters on a substrate are read by producing relative movement between the substrate and a reading head, the head having individual upper, middle and lower horizontal segment detectors and upper and lower vertical segment detectors, to receive reflected light, the head including at least one aperture to direct light on to the substrate. The characters may be embossed or debossed characters on, e.g. a credit card, or dark print on a light background. As described, when the credit card is inserted into a holder, two photo-cells detect its presence and cause a reading head to be reciprocated horizontally along the card and back (or the card may be moved or both), a groove in the head engaging the characters mechanically to position the head vertically. Six pairs of light pipes are used to detect the presence or absence of six strokes from which each character can be formed, one pipe of each pair directing light at the relevant position on the card and the other carrying any reflected light to a respective photo-cell. During movement in one direction of the head, a decoder and encoder recognize each character and detect the intercharacter spaces, from the outputs of the six photo-cells. A check may be made that successive characters detected are separated by detected spaces, and that the characters and spaces remain detected for at least a minimum interval, and two detected spaces without a detected character between can cause at least one rescan. The encoder identifies each character and space to a shift register which feeds a buffer memory. Register and memory are both controlled by detection of the spaces. The memory feeds a memory at a central location where a comparison check is performed against stored data to notify the input station if the card is acceptable. Further stations may communicate with the central location similarly.
